HOISTING MACHINERY.

SPECIFICATION forming part of Letters Patent No. 664,073, dated December18, 1900;

Application filed June 25, 1900.

To all whom it may concern.-

Be it known that I, HANS C. BEI-IR, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have invented a new and useful Improvement in HoistingMachinery, of which the following is a specification.

My invention relates to improvements in hoisting apparatus for mines, inwhich the hoisting-rope passes from the pit or mineshaft over a pit-headsheave to a hoistingdrum extending in a plane at an angle to saidsheave. In apparatus of this character it is desirable that the ropeshall be wound in a single layer upon the drum, and it is also desirablethat the diameter of the drum shall be as small as other requirementswill admit in order that the size of the driving-engine may not begreater than necessary or that expensive and otherwise objectionableintermediate gearing between the engine and drum may be dispensed with.As the angle of extent of the rope between the pit-head sheave and thedrum changes while the rope is being laid on or paid off of the drum, itis neces sary where long drums are employed to provide means forpositively guiding the rope to and from the rope-leading face of thedrum, and it is also necessary that the sheaves shall all extend in thesame plane to prevent undue wear upon the rope.

My objectis to provide improved rope-guiding means between the pit-headsheave and drum whereby the bends of the rope will be reduced to aminimum, the rope will be guided to the drum and laid thereon in asingleeven layer without friction of the rope against itself, and therope-guide sheave at the drum will extend at all times in the plane ofthe pit-head sheave.

To the above ends my invention consists in the general construction ofmy improved ropeguiding apparatus, as well as in details of constructionand combinations of parts, all as hereinafter set forth and claimed.

In the drawings, Figure 1 is a broken view showing my improvements inside elevation; Fig. 2, a top plan View of a double hoistingmachineconstructed with my improvements for a two-compartmentmine-shaft; Fig.3, an enlarged broken section taken on line 3 of Serial No. 21,488, (Nomodel.)

Fig. 2; Fig. 4, a broken and enlarged section of the mechanism adjacentto the drum; Fig. 5', a broken detail section taken on line 5 of Fig.4:, and Fig. 6 an enlarged sectiont-aken on line 6 of Fig. 4c.

A denotes a gallows-frame or the like above the two shaft compartmentsor pits B, which in Fig. 2 are shown spread apart for convenience ofillustration.

C C are the pit-head sheaves, D D the hoisting-drums, and E E therope-guide sheaves.

F F are beams or frames on the opposite endsof which the sheaves C and Eare journaled. Each beam F may be trussed between its ends, as shown,and at its upper end is rigidly secured to a horizontally-swingingpivot-frame F. Firmly supported upon the upper end of the gallows-frame,centrally above each pit or compartment B, is a bedplate G, having acentral opening a, surrounded on the upper side by a cylindricalbearing-boss at, having a smooth outer face. Extending through theopening a is a hollow liner d of wood or other comparatively softmaterial. Centrally between the sides of the frame F is a bearing-sleeveb, fitting closely around the boss a and resting on a roller or ballbearing 19, interposed between it and the bed-plate. On the forward partof the scaffold is a track 0, and the frame F is provided with rollersc, resting on said track. The pit-head sheave C is journaled in bearingsd on the frame F to extend in a plane parallel to and centrally of thesides of the beam F. The rear edge or rope-leading face of the sheave Cis centrally above the opening through the liner a The rope-guide sheaveE at its forward edge or rope-leading face is in a plane approximatelyvertical and tangential with relation to the rope-leading face of thedrum D. The two drums are upon the same crank-shaft H, which is drivenfrom an engine I. As it is usual in a construction in volving two drumsto have one lay on or wind up the rope as the other pays the rope off,one beam F is longer than the other, so that one rope-guide sheave willbe above the inner edge of one drum while the other ropeguide sheave isabove the outer edge of the other drum. Below the lower forward endportion of each beam or frame F is a station ary frame K, provided onits upper side with a horizontal track 6, preferably curved in the arcof acircle of which the liner a is the center. The face of the track 6may be inclined, as shown in Fig. 1, to extend in a plane parallel withthe inclined beam F. On the under side of the lower forward end portionof the frame F is a roller f, at which it rests upon the track 6.Journaled in the frame K and extending parallel with the drum D isascrewshaft 9, provided at one end with a pulley or sprocket wheel g. Thedrum is provided with a trunnion h, shaped to form a pulley or sprocketwheel in the plane of the pulley or sprocket wheel g, and a belt orchain It gears the two together. 0n the screw-shaft g is a traveling nut1', having an arm 1' loosely and pivotally connected at its free end tothe under side of the beam F at i". The nut t', with its arm t", is inthe nature of a swinging link pivoted on the screw-shaft g, permittingrelative longitudinal movement of the beam. The gearing between the drumD and screwshaft 9 is such that in the turning of the screw-shaft thenut will be caused to travel at a speed which will move the rope-guidesheave a distance approximately equal to the width of the rope in eachrevolution of the drum. Owing to the length of the beam F it moves atits free end in the arc of a circle of great diameter, whereby themovement of the sheave in the direction transversely of the drum is butslight and not enough to in any way interfere with the proper laying onor paying off of the rope.

In operation as the rope is wound upon or paid off from the drum thebeam or frame F is caused to swing in an are nearly parallel with therope-leading face of the drum, as described, the frame F swinging uponthe pivot at a. Thus the ropedeading face of the pithead sheave willnever change with relation to the opening in the liner a through whichthe rope X depends into the mine-compartment, and the sheaves C and Ewill always remain in the same plane with relation to each other,whereby there will be no friction of the rope against the sides of thegrooved faces of the sheaves. Furthermore, by thus mounting the framewith its pivot about the rope X only two sheaves are necessary betweenthe mine-compartment and drum, thus dispensing with additional bends ofthe rope, which are objectionable for obvious reasons.

While I have shown and described my improvements in the form in which Iprefer to provide them, they may be variously modified in the matter ofdetails of construction without departing from the spirit of myinvention as defined by the claims.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the pit-head sheave, over which the rope passesimmediately from the mine-shaft, the rope-winding drum, a rope-guidesheave adjacent to the windingdrum, a swinging frame, carrying both saidsheaves, pivoted above the mine-shaft in line with the rope dependinginto the shaft and operating to hold the sheaves approximately inalinement with each other throughout the movement of the frame.

2. The combination with the mine-shaft, gallows-frame above the shaftand windingdrum at one side of, and extending at an angle to, the shaft,of a swinging frame pivoted upon the gallows-frame to swing at its freeend in an arc the center of which is in or approximately in line withthe rope depending into the shaft, a pit-head sheave journaled on theswinging frame with its rope-loading face on the axis of said frame, anda rope-guide sheave on the swinging frame adjacent to the drum andapproximately in alinement with the pit-head sheave.

3. The combination with the mine-shaft, gallows-frame above the shaftand rope-winding drum at one side of, and extending at an angle to, theshaft, of a swinging frame pivoted upon the gallows-frame around therope depending into the shaft, a pit-head sheave journaled on theswinging frame with its rope-leading face on the axis of the swingingframe, and a rope-guide sheave on the free end portion of the frame,adjacent to the drum and approximately in line with the pit- .headsheave.

'4. The combination with the mine-shaft, gallows-frame above the shaftand windingdrum at one side of and extending at an angle to the shaft,of a swinging frame pivoted at one end portion upon the gallows-frameand extending in a downward-inclined direction with its free endadjacent to the drum and swinging at its free end in an arc the centerof which is approximately in line with the rope depending into theshaft, a pit-head sheave journaled on the swinging frame with itsrope-leading face on the axis of said swinging frame, and a rope-guidesheave on the free end portion of the swinging frame approximately inline with the pit-head sheave.
